Abstract

This disclosure provides systems, methods, and apparatus for incorporating a touch sensor into a display device. In one aspect, a display device can be formed from two opposing substrates coupled by an edge seal. An aperture plate can be fabricated on a rear surface of the front substrate. Apertures corresponding to display elements can be formed through the aperture plate. Conductive layers can be deposited over the rear surface of the front substrate and patterned to form portions of a capacitive touch sensor. The conductive layers also can be patterned to include apertures aligned with the apertures formed in the aperture plate. The apertures formed through the conductive layers may permit the conductive layers to be formed from light-blocking material without substantially impacting the optical quality of the display.
